Samsung Galaxy S3 Extended Battery Case Reviews: Worth Buying?

The Samsung Galaxy S3 is one of the most popular smartphones in the world, so it can't be surprising that people are looking into finding an extended battery for the device. In fact, considering the S3 helped Samsung and the Galaxy S series shoot past Apple and the iPhone, it's to be expected.

As with anything popular, though, the success of the Galaxy S3 has meant that even when it comes to looking for an extended battery, the options are seemingly endless. Many of the peripherals available offer the battery extensions built into the case, but are they any good? Let's take a look at three items on Amazon and see what users thought of their performance.

Based on user reviews, it looks like the Supreme High Quality Glossy White 3200mAh Battery Pack Case for the Galaxy S3 isn't actually of supreme quality at all. Fortunately, it looks like most people have stayed away from the device, considering that it only boasts five reviews and they're all negative.

One user complained that the case can't even fully charge your phone if it dies, while another said that the lack of protection on the sides and corners means that the Galaxy S3 will crack easily.

Consider This

Now that we have that out of the way, let's move on to something people might actually consider buying for their Galaxy S3. The YESOO-GS3 has generally positive reviews, and amassed a four-star rating based on about 90 reviews. And at $15.99, it's 10 bucks cheaper than the "Supreme High Quality" one.

"Very Cheap price and HIGH QUALITY!" Oregon Amazonian wrote. "The new plastic back fits perfectly, the battery is snug and much longer life (double). It also comes with a quality well-fitted rubber protective cover! I am very impressed!"

Another user said that the battery life is extended to 36 hours, but complained that the case cracks easily (they had to have it replaced twice).

Cream of the Crop?

One of the best-reviewed extended batteries is the Hyperion in Sapphire Black. It costs about $23, but it looks like it's well worth the extra few dollars if the user reviews are to be believed.

"The battery is twice the standard GS III component and delivers a great charge," J. Lee wrote. "I'm business/semi-power user who can now go two full days without a charge if necessary."

"I am a heavy phone user and this battery is utterly amazing," Tyronius wrote. "I unplugged my phone at 830 am and now at 1 am i have 30% still. Today I gave it a beating by using navigation for a couple hours, watching netflix, texting a ton, playing high demanding games, surfing the internet, and talking on the phone for a couple hours."

There are obviously a lot of choices when it comes to extended batteries for the Galaxy S3. Feel free to let us know your experiences with the peripherals in the comments. Have you tried any of these three? Or maybe you prefer a different kind?
